 Trustindex verifies that the original source of the review is Google.  I couldn't be more pleased with my experience with Combined Services. From the moment I called, their customer service was outstanding—friendly, professional, and quick to respond. The technician arrived on time, was incredibly knowledgeable, and took the time to explain everything in a way that I could understand. They diagnosed the issue with my AC unit quickly and had it up and running again in no time. What really impressed me was their honesty—no upselling or unnecessary repairs, just straightforward, quality service at a fair price. It's clear that they care about their customers and take pride in their work. I highly recommend Combined Services to anyone looking for reliable and trustworthy heating and cooling services. I’ll definitely be calling them again for future maintenance! ALSO… do yourself a favor and talk with Ken!! I had the pleasure of working with Ken, the owner, and I can’t say enough great things about him. From start to finish, he was professional, knowledgeable, and genuinely cared about getting the job done right.

Thanks to Scott for coming out and helping fix our AC during this awful heat wave and offering Emergency services while being so generous. It’s surprising that somebody would be this fast on a weekend when services aren’t typically provided, which makes this company a genuine gem!

 Trustindex verifies that the original source of the review is Google.  Extremely pleased with the service on my AC. I will ONLY use Combined Services for HVAC work going forward! The HVAC tech, Dan, was polite, smart, explained everything patiently and with good humor, accurately diagnosed the issue, and professionally did the repair. The "peace of mind" Dan conferred came at no additional cost -- but it's priceless! Thank you!!

 Trustindex verifies that the original source of the review is Google.  We are so thankful for Combined Services.   Our furnace stopped working.  They came out and troubleshooted a few different issues.  Repaired our furnace and kept us from having to buy a new one.  The expertise and professionalism they showed us was amazing.  Will definitely use them again.

 Trustindex verifies that the original source of the review is Google.  My brother recommended Combined Services to me, after some good 'feedback' he received from another coworker who was also a happy customer. I'm really happy with the service I received.  (A/C unit replacement) I should mention – Ed did not try to 'oversell' what needed to be replaced.  This is important & very much appreciated !! The Installers showed up 'as scheduled', right on time. (A bit early, actually.) :-)  They took the time to explain to me what was being done as part of the replacement & install. Everything worked A-OK after the install, no hiccups. Would I use them again ??  Of course !! - Nick
